  • Applications

    16,18-Tritriacontanedione (CAS 24514-86-1) is often viewed as a synthetic intermediate for specialty polymers and coatings; in plastics and coatings applications it can function as a plasticizer or processing aid to improve processing and film properties. Its long aliphatic chain with carbonyl groups also suggests potential as a lubricant additive for high-load, low-shear applications. In fragrance and cosmetics, it may be evaluated as a fragrance ingredient or fixative due to its lipophilic character, and it could be used as a wax-like component or processing aid in cosmetic formulations. Additionally, it can serve as an intermediate for the synthesis of high-performance materials or as a component in adhesives or coatings formulations to modify compatibility and film formation.
